8 Claims. (01. 72-86) This invention relates to wall coping of p the type comprising clay sections adapted to be fitted together with a tongue on one end of each section engaged in a socket in the abutting end of an adjacent section. p

Heretofore wall coping of this type has been made commercially in which the socket is provided in an outwardly flared formation at one end of each coping section into which a plain end oi.

3.0 each coping section is adapted to fit. This type of coping accordingly has a series of spaced projections along the top of the wall.

It is desirable to have a wall coping which is smooth and free of such spaced projections at the joints between the coping sections and it has been proposed in the past to provide such coping in which the coping sections are formed so as to ship-lap at the joints. In clay copings, however, this is objectionable since the coping sections must be made too thick to provide suflicient material in the ship lap formations to be economically and effectively fired in the manufacture of such coping.

One purpose of the present invention, therefore, is to provide wall coping of the type described with improved tongue and socket joint formations whereby a smooth jointis provided while maintaining the coping thickness desirable for economical and effective manufacture.

Another purpose of the'invention is to provide improved means in sectional wall coping for more eifectively securing the coping sections on a wall, a means which while capable of utilization in different types of wall copings, is especially advantageous in the coping structure described in the preceding paragraph.

The foregoing and other purposes of the invention are attained in the wall coping illustrated in the accompanying drawing and described below. It is to be understood that the invention is not limited to the specific form thereof illustrated and described.

Of the accompanying drawing,

Figure 1 is a plan view, partly broken away and 5 in section, of a wall coping embodying the invention;

Figure 2 is an elevation thereof partly broken away and in section;

Figure 3 is a. perspective view of the tongue end of a coping section embodying the invention;

Figure 4 is an end view of the socket end of said coping section;

Figure 5 is a section on line 5--5 of Figure 2; and

Figure 6 is a section on line 6-6 of Figure 2.

Referring to the drawing, the numeral 10 designates a wall coping section of fired claywhich may be of the usual thickness for economical and effective firing and which may be of-con'cavo convex formation in section 'as shown, a concave groove extending along the under sidetherecf, and which may be provided with depending flanges 11, 11 for overlapping the joint betweenthe coping and the wall on which it is applied.

Each section has at one end thereof a portion 55 12 extending'inwardly of the groove on the under side of the coping provided with an extended tongue 13, shaped to fit into thesaid groove at the opposite end of an adjoining coping section, the said opposite end of each. section being left open and unobstructed to provide a socket for said tongue. The width of this tongue is such that the depending flanges 11 of an adjoining section will clear the tongue and fit in juxtaposition with the depending flanges of an adjoining section.

In the groove on the under side of each coping section there are formed ribs 14,14 for interlocking each section on the top of a wall. These ribs do not extend all the way to the socket end of the coping section, being cut-away as at 14, 14 (Fig. 2) to clear the tongue of'an adjacent section. These ribs are preferably placedcomparatively close to the flanges 11 and the sides thereof opposite the inner faces of' the flanges are undercut as shown, so that the coping sections may be jointed to the walls with cement or mortar as indicated at l5, 15 on which the coping sec.- tions are placed, the mortar. flowing into. the

spaces between the ribs 14 and the flanges 11 and dovetailing the coping sections to. the top of a wall structure (see Figures 52 and 6).

The improved coping sections may .be easily and effectively jointed to provide an improved joint preventing water from finding its way 5 downwardly into the wall structure. Cement: or mortar is applied on top of the tonguefl13 of a previouslymounted section and upon applicationof a succeeding section-to the wall is squeezed between the coping members and up into the joint between the abutting ends of the coping sections above the tongue and down about the edges of the tongues between these and the flanges 11,11 (see Figures 2 and 5).

Modifications of the invention may be resorted .1105 to without departing from the spirit thereof or the scope of the appended claims.

What is claimed is:-

1. A coping unit comprising a substantially fiat body portion of arcuate cross-section and having 1 l0 longitudinally extending depending flanges along its opposite edges, depending ribs upon the under side of said body portion and extending longitudinally in spaced relation with respect to said flanges, said ribs terminating short of one end of said body portion, a depending wall at the opposite end of said body portion and with which the ad j adentendsoifjsaid ribs are e oni1 ected, and an mints longitudinally extending tongue on the outer end of said Wall and disposed in a plane substantially beneath the under suriaee of said body portion. v
